Note: the original question has been edited for brevity. The questioner reported that her neighbors seem to be mocking her.
Remember that men living in apartments do tend to laugh a lot and raucously. And they can only interfere with your TV if it is Bluetooth or wifi enabled. Check your connections and make sure your devices are only connected to your own router.
My advice is to determine if this is happening, and if so, collect proof. Get yourself a cheap bug detector and look for hidden cameras. If you find anything, go to the police. If you are living in rented accommodation, report your findings to the landlord as well. Also, think about moving. This is not good for your wellbeing at all.
